“Flatland: A Romance of Many Dimensions” was originally an 1884 novella by the theologian and mathematician Edwin A. Abbott. It is popular among mathematics and computer science students, and considered useful reading for people studying topics such as the concept of other dimensions. As a piece of literature, Flatland is respected for its satire on the social hierarchy of Victorian society. As of this writing there have been three films made based on this novel, of which “Flatland: The Film” is the latest.
